Abstract: 204,329. Br³ll, K. Sept. 21, 1922, [Convention date]. Addition to 178,463. Jib cranes. - Comprises improvements in or modifications of the construction of boom-winch described in the parent Specification, in which the boom was raised, lowered, and slued by the manipulation of three drums. In the present construction, in which the whole of the operations are conducted by a single handle, the hoisting motor 1 drives a shaft 4 which is connected to the hoisting drums 11 through spur gearing 9, 10 and a combined brake and clutch 6. When the controller handle is moved to " hoist " the hoisting motor is started, and an auxiliary motor 41 also is operated to rotate a tappet-carrying shaft 40 to close the clutch 6 and release band brakes 7 and 2. When the load is to be slued, the controller handle is moved so that the shaft 4 still is driven from the hoisting motor, but the motor 41 is driven in the reverse direction, as a result of which the clutch 6 remains open and braked, no drive being transmitted to the drum 11. At the same time the auxiliary motor 42 is energized to rotate the controlling shaft 43 in one direction or the other to manipulate clutch-andbrake mechanism so that one or other of the slueing drums 19, 20 is driven from the shaft 4.

Title: Improvements in or relating to the manufacture of mono-calcium citrate dihydrate
IPC: A61K33/06
Filed: 1944-11-23
Abstract: Solid mono-calcium citrate dihydrate is prepared by mixing one mole. of solid calcium oxide, hydroxide or carbonate with at least two moles. of anhydrous or hydrated citric acid and only sufficient water to provide a fluid paste whereby reaction ensues with the generation of heat, the mixture being transformed into a solid cake of mono-calcium citrate dihydrate and any excess of citric acid over said two moles.  To obtain a wholly water-soluble product a proportion of at least 2.1 moles. of citric acid is used.  The cake of calcium citrate may be freed from water or excess citric acid or both by treatment with a non-aqueous organic solvent in which the citrate is insoluble, for example, acetone, methyl to amyl alcohols and various ethylene glycol and diethylene glycol monoalkyl ethers. The calcium citrate may be used in baking powders and pharmaceutical remedies (see Group VI). Examples describe the preparation of calcium citrate with or without citric acid by mixing 1 mol. calcium carbonate and varying amounts from 2 to 3.1 moles. of anhydrous citric acid with water to form a paste and drying the resulting cake, substantially pure mono-calcium citrate being obtained by retracting excess citric acid, when present, with acetone.ALSO:Internal remedies comprise mono-calcium citrate dihydrate, with or without citric acid, and a salt of carbonic acid, for example, sodium bicarbonate, alone or with an acidic phosphate such as calcium phosphate.  The compositions give effervescent solutions in water.  The monocalcium citrate dihydrate, whose preparation is described (see Group IV), may be used alone or with citric acid as a baking powder component.

Title: Improvements in the manufacture of electron emitting bodies
IPC: H01J9/04
Filed: 1927-09-12
Abstract: 288,561. Lederer, A. April 12, 1927, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes. - An electron-emitting wire or ribbon is formed by an alloy or compound of more than 2 per cent of thorium with one or more metals of the platinum group, preferably osmium to which highly refractory metals, such as tungsten, may be added. A mixture of finely-divided osmium or a compound of osmium, thorium or thorium oxide, and a binding agent such as collodion, tragacanth, gum or sugar is formed into a paste and squirted to form a filament which is subjected to heat treatment, either by passage of current through it, or by external heating, in a gas or high vacuum, care being taken to exclude oxidizing gas or vapour. Preferably a paste is made of 10 parts by weight of powdered osmium, 10 parts by weight of thorium oxide and 6 parts by weight of amyl acetate of collodion. The squirted filaments are heated to a temperature above the melting point of thorium, 2000‹ K., and preferably to 2400-2500‹ K. During this operation the oxide is reduced and an alloy or compound of thorium and osmium is formed. The filament is then heated to a temperature of 3000‹ K., close to the melting point of osmium, to consolidate the alloy. Heating may be effected in carbon monoxide at a pressure of 150 mm. of mercury. Tungsten may be added to the mixture but the melting point of the alloy is lowered thereby. A suspension of metallic osmium and thorium oxide or other compound may be applied to a core of tungsten, or the mixture may be deposited by electrolysis, the coated core being heated subsequently.

Title: Improved feeding apparatus for textile fabric
IPC: F26B13/12
Filed: 1953-08-31
Abstract: 742,429. Feeding webs. SAMCOE HOLDING CORPORATION. Aug. 31, 1953 [Oct. 23, 1952], No. 24054/53. Class 100 (1). [Also in Group XIII]  In a reel-type dryer for a continuous web of textile fabric having a plurality of rotary reels 11, 12, 13 of air pervious material adapted to receive the fabric 15 and support it on their surfaces during a large part of its travel through the machine, there are provided means for rotating the reels, vertically displaceable means for receiving and supporting, tension-free, the fabric as it leaves the surface of each reel and for delivering it to the successive reel on demand, means for adjusting the rotating means for the reels to vary individually the speed of each reel, and means controlled by movement of the fabric-receiving means of each reel to govern the speed of the succeeding reel. Fig. 1 shows one end of the machine which comprises a number of reels 11, 12, 13, &c., mounted on a frame 10. The fabric web 15 is drawn into the machine by a roller 16 driven by a belt 27  from a shaft carrying a pulley 19 driven in turn from a motor 25 by belt 26. A belt 18 passing over the pulley 19 drives a number of pulleys 22 each of which is connected by belts 32, 35 and gears 38, 39 to drive one of the reels. Between belts 32, 35 is a variable-speed pulley 31 mounted on a shaft 33 and controlled as to ratio by an arm 34 having a pin 41 at its free end engaged in a curved guide slot 42 in an arm 43 mounted on a spindle 44. Slidably arranged on vertical guide rods 52 on each side is a J- shaped open mesh box 50 having a projecting rod 53 on each side connected by a chain 54 passing over a pair of pulleys 55, 56 to a counterbalance weight 57. Pulleys 55 are connected to a common cross shaft which serves to prevent transverse tilting of the box 50. One of the pulleys 56 is mounted on the shaft 44 and serves to swing the arm 43 as the box rises and falls. The fabric 15 passes from roller 16 into the upper entrance of the box 50, crumpling up at the bottom as shown and is withdrawn through the lower opening by the reel 11. The arrangement is such that an increase in the weight of fabric in the box 50 causes rotation of the shaft 44 and displacement of the arm 34 to increase the ratio of the variable-speed pulley 31 so that the reel 11 is driven at a greater speed. By this means the length of fabric in the box is maintained substantially constant. The fabric leaving reel 11 passes into a similar box 60 controlling the speed of reel 12. After passing under reel 12 the fabric is lifted by a driven roller 71 and deposited in another box 70 controlling the speed of the next reel 13 in the same manner. In this way the fabric is dried (by drying means provided in the reels) without being subjected to tension. Specifications 540,054 and 742,431 are referred to.
